The "Dual" company has been producing antennas for more than 25 years.

We do not use "amateur" programs like EZNEC Pro/4 - NEC4.2 engine, 4NEC2, EZNEC, YO or AO.

We perform the design work using the latest professional full-3D electromagnetic modelling software.This enables us to accurately include the influence of the boom, insulators, baluns, feed point, connections, etc
